Network-assisted channel selection and power control for mobile devices

Abstract

Facilitation of a network assisted device-decided system can increase throughput of D2D devices and the link reliability of macrocells. In a network assisted device-decided system a macrocell can broadcast resource allocation data to D2D devices. The D2D devices can then select channels and adjust transmission power to offload traffic from the macrocell, thus creating a high spectrum efficiency with low power.
